ATEENT- FOLDING SPRING-SEAT.

SPECIFICATION forming part of Letters Patent No. 620,816, dated March'7, 1899.

Application filed June 4, 1998. Serial No. 682,570. (No model.)

To all whom it may concern.-

Be it known that I, FRANK G. WEsTLANn, a citizen of the United States,residing at Mc- Cook, in the county of Red Willow and State of Nebraska,have invented certain new and useful Improvements in FoldingSpring-Seats; and I do hereby declare the following to be a full, clear,and exact description of the in vention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to folding seats, and

is in the nature of an improvement upon a former device of a similarnature, for which Eetters Patent No. 602,788 were granted to me April19, 1898.

The folding seat contemplated in this invention is designed, like thatdescribed in the patent referred to, for use especially inlocomotive-cabs and other circumscribed spaces,

wherein a seat is of great convenience to the engineer and it is at thesame time necessary that the seat can be folded compactly out of the waywhen not required.

The present invention relates particularly to the means for holding theseat in position for use and instantly releasing the same when no longerrequired.

The detailed objects and advantages of the invention will appear in thecourse of the subjoined description.

The invention consists in certain novel features and details ofconstruction and arrangeinent of parts, as hereinafter fully described,illustrated in thedrawings, and incorporated in the claims.

In the accompanying drawings, Figure l is a perspective view showing theimproved seat in its operative position. Fig. 2 is a detail verticalsectional view of the same; and Fig.

3 is a face view of the sliding support with the seat and its bracketsomitted, showing the latch-bars.

Similar numerals of reference designate corresponding partsin all thefigures of the drawings.

Referring to the drawings, 1 designates a sliding seat-support whichis'mounted to slide up and down in a suitable frame comprising uprightside bars 2 and cross-bars 3, connect ing the side bars at top andbottom. The said frame is designed to be secured to the wall of the cab,and the support 1 is adapted to slide up and down thereon in order tobring the seat (indicated at 4) to the proper height. The seat issupported upon a pair of brackets or arms 5, provided at their innerends with pendent lugs or extensions 6 in the shape of elbows. Thesupport 1 is provided at suit able points with projecting ears '7,having openings for the reception of a rod 8, which passes therethroughand also through openings at the elbows of the bars or arms 5, asclearly shown in Figs. 1 and 2. At one side of each ear 7 the slidingsupport 1 is provided with a slot or aperture 9, of a size sufficient toadmit of the rocking of the pendent extension 6 therethrough when thebrackets 5 fold downward, as indicated in dotted lines in Fig. 2. Inorder to lock the seat in position for use, I provide a pair oflatch-bars 10 and 11, pivotally connected to the support 1 at the points12. One of the latch-bars 10 is extended obliquely, as at 13, so as topass over one of the lugs 7, where it is further extended to form ahandle 14. ,The latch-bar 10 is also provided with a slot 15, in whichis received a stud 16 at the extremity of the latch-bar 11, saidlatch-bar being offset, as indicated at 17, so that its inner end mayoverlap one side of the bar 10, while its outer portion lies in the sameplane with the bar 10. Normally the latch-bars 10 and ll'lie across thelower ends of the slots 9, and when the brackets 5are in a horizontalposition the latch-bars 10 and 11 interpose themselves between theextensions 6 and the adjacent side of the support 1, as clearly shown inFig. 2, thus locking the brackets 5 in their horizontal position andholding the seat ready for use. By lifting the handle 14 both latch-barsare moved downward at their free ends, passing out from behind thependent extensions 6, and thus allowing said extensions to swing throughthe slots 9, the seat thus dropping to a pendent position alongside ofthe support 1.

In connection with the seat 4 I employ a back-support 18, mounted on theupper forked end of an arm 19, the lower end of which is bent andextended obliquely and provided with a pintle, which is journaled in asleeve secured to the adjacent face of the sliding support 1, asdescribed in my former patent above referred to.

It is unnecessary to enter into a description of the back-support 18 andthe specific connection between the sliding support 1 and the stationaryframe, as said parts are fully described in my prior patent and form 110part of the present invention, which relates to the particular means forlocking the seat in position for use and releasing the same when nolonger required.

It will of course be understood that various changes in the form,proportion, and minor details of construction may be resorted to Withoutdeparting from the principle or sacrificing any of the advantages of theinvention.

Having thus described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is-

1. In afolding seat, the combination with a vertical support having anaperture, of a seatbracket having a direct pivotal connection therewith,an elbow extension on said bracket adapted normally to work through theaperture in the support, and a latch-bar pivotally mounted on thesupport, adapted to engage said extension and provided with a lever-armextending above the plane of the pivoted seatbracket.

2. The combination with a vertical support provided with apertures, of apair of seatbrackets pivotally connected thereto, extensions or elbowson said brackets, arranged to work through the apertures in the support,latch-bars pivotally mounted on the support and extending across saidslots, so as to engage the extensions on the brackets, and means forsimultaneously operating said latchbars, sub- Witnesses:
